A tube of uniform cross section is used to siphon water from a vessel V as shown in the figure. The pressure over the open end of water in the vessel is atmospheric pressure (P_(0)) . The height of the tube above and below the water level in the vessel are h_(1) and h_(2) , respectively. Given h_(1) = h_(2) = 3.0 m , the gauge pressure of water in the highest level CD of the tube will be

A horizontal tube has different cross sections at points A and B . The areas of cross section are a_(1) and a_(2) respectively, and pressures at these points are p_(1)=rhogh_(1) and p_(2)=rhogh_(2) where rho is the density of liquid flowing in the tube and h_(1) and h_(2) are heights of liquid columns in vertical tubes connected at A and B . If h_(1)-h_(2)=h , then the flow rate of the liquid in the horizontal tube is

The angles of elevation of the top of a tower from the top and foot of a pole are respectively 30^(@) and 45^(@) .

(h_(T)-h_(P))/(sqrt(3)+1)=(h_(P))/(2) 3. (2(h_(P)+h_(T)))/(h_(P))=4+sqrt(3) Select the correct answer using the code given below.

Suppose water is used in a barometer instead of mercury. If the barometric pressure is 760 mm Hg , what is the height of the water column in the barometer at 0^(@) C . The densities of water and mercury at 0^(@) C are 0.99987 g cm^(-3) and 13.596 g cm^(-3) , respectively. Strategy : The prtessure exerted by a column of liquid h whose density is d is hdg . Because the pressure are equal , we can equate the expressions for water (W) and mercury (M): h_(W)d_(W)g = h_(M) d_(M)g or h_(W)d_(W) = h_(M)d_(M) Rearranging gives (h_(W))/(h_(M)) = (d_(M))/(d_(W)) This implies that the height of the liquid column in inversely proportional to its density . Solve the equation to find the height of the water column, h_(W) .
